Chris Brown could face up to 14 years behind bars if he's found guilty of assault with a deadly weapon.

The star was arrested and charged yesterday following an 11-hour stand off with police at his Tarzana mansion.

Police were alerted to the property at around 3am after a woman called 911 and claimed Brown had threatened her with a gun.

Legal expert, Troy Slaten, has spoken to E!News about the charges and stated that the maximum penalty for assault with a deadly weapon is four years in state prison, but this could be enhanced because of the alleged use of a gun in the crime.

He explained: "Assault with a deadly weapon is a possible felony in California, and there is an significant enhancement for using a firearm in the commission of a crime.

"An enhancement means that, if convicted and found true, your prison sentence is increased or 'enhanced."

Slaten added: "So theoretically 14 years is the statutory max. But that would be very unlikely without a long rap sheet."

Brown was previously convicted for felony assault after an attack on then-girlfriend Rihanna in 2009.

The arrest could also have an impact of Brown's custody arrangements for daughter Royalty with her mother Nia Guzman.

Slaten predicted that the arrest could be used as the basis for additional proceedings in family court and that Guzman could well push for sole custody of the two-year-old.

"Guzman doesn't have to prove to the family court that Brown is guilty 'beyond a reasonable doubt,' the standard used in criminal cases," Slaten said. "She only has to prove by 'clear and convincing' evidence that the bests interests of the child are served by her requests."

A tense stand-off

Brown, who has claimed to be innocent of the charges, was released on a $250,000 bail.

His lawyer Mark Geragos later took to insist the allegations were "false", writing: "Thanks to everyone for their support and well wishes. Chris is out and well. The allegations against him are demonstrably false."

He is now expected to appear in court on September 20, the records show.

Officers surrounded the singer's home on Tuesday following a pre-dawn 911 call from a woman - later named as beauty queen Baylee Curran - who claimed he had pointed a gun at her.

Brown, 27, denies any wrongdoing and said on Instagram posts that he had woken up to find police outside and that they would need a warrant to enter the Tarzana property.

Lieutenant Ramirez said earlier: "This morning, around three o'clock, officers responded to a radio call for a woman requiring assistance.

"The incident involved the residence of Mr Chris Brown, where officers responded and met with that person."

Police spent hours waiting outside Brown's home before obtaining a search warrant and beginning a search of the sprawling premises in the early afternoon.

The singer's entourage began to emerge at around 12:40pm, before they were interviewed by police.

The singer himself followed two hours later, leaving the building at around 2:38pm wearing a white t-shirt, black jeans and a red hat.

He looked in good spirits as he spoke to law enforcement and a second person, believed to be his lawyer Mark Geragos.

A huge police presence had been at the mansion since early this morning, with the first time arriving at around 3am following reports he threatened Curran with a gun.

It was reported on Tuesday by TMZ that the singer was being investigated on an allegation of criminal assault, after Curran claimed he threatened her with a gun while at an LA residence, prompting her to call 911.

It was previously reported that authorities were waiting for a search warrant to be granted and were expecting the singer to "surrender" himself.

Brown's lawyer, Mark Geragos, is believed to have gone into the home at 12:30pm [PDT].

Several people have been seen leaving the property and coming out to the gate, where they've spoken to officers.

From inside the house, Brown posted a string of videos on Instagram, venting his frustration over the situation.

Soon after images of police outside Brown's house were posted to social media, with the singer then insisting he had done nothing wrong in an expletive laden Instagram video.

The woman at the centre of the drama was quickly identified as beauty queen Curran.

She revealed she had "partied" with Brown in the past and said he had always been "nice".

On Monday night she claims to have gone to his Tarzana mansion where they hungout in a hot tub and were having fun, until she admired a piece of jewellery worn by a member of Brown's crew.
